Marlinton’s center stands about 2,460 ft above sea level. Within three miles the land runs from 2,120 ft to 3,490 ft, a difference of 1,370 ft: steep hill country. The highest named summit within 15 miles is Red Spruce Knob, about 4,720 ft, 8 miles north-northwest.
Under the town center the state geologic map shows Pocono Group (sandstone), from the Carboniferous, 324 to 359 million years old.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Marlinton reaches the Gulf of America by way of the Greenbrier, the New River, the Kanawha, the Ohio and the Mississippi: about 1,950 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marlinton; river miles along the main stem, rounded.
